The structure and properties of niobapyrimidinium complex were examined by density functionaltheory method (mpw1pw91). The effect of solvent on the structural parameters, frontier orbitalenergies and hyperpolarizability (tot) of this molecule has been explored. The thermodynamicproperties of the title compound at different temperatures have been calculated. Also, the parasubstitutionseffect on ...

This study employs data envelopment analysis approach to construct the meta-frontier global technical efficiency of energy use index and global technical efficiency of CO2 emission control index to measure the energy use efficiency and CO2 emission control efficiency at country level. Destruction of these efficiency indices into pure technical efficiency and scale efficiency sub-indices is to c...

Current research depicts specific modes of immunity and energy metabolism as being interrelated at the molecular, cellular, organ and organism level. Hence, whereas M2 (alternatively-activated) macrophages dominate insulin-sensitive adipose tissue in the lean, M1-skewed (classically-activated) macrophages accumulate in parallel to adiposity in the obese, and promote inflammation and insulin res...

Metamaterials, artificial composite structures with exotic material properties, have emerged as a new frontier of science involving physics, material science, engineering and chemistry. This critical review focuses on the fundamentals, recent progresses and future directions in the research of electromagnetic metamaterials. An introduction to metamaterials followed by a detailed elaboration on ...

ritic Tanacs Ferenc has described “Hajónapló” [Logbook] (1987), a short story written by Ottlik Géza, as “a Borgesian exercise in transfictionalizing certain obsessive paradoxes of national identity, authorship, writing and language” (168). Certainly, Ottlik seems to have faithfully adopted the skewed world vision, the penchant for linguistic invention and a mode of tongue-in-cheek historical (...

Cross language-image retrieval is a problem of high interest that is at the frontier between computer vision and natural language processing. State-of-the-art methods learn a common space with regard to some constraints of correlation or similarity from two textual and visual modalities that are processed in parallel and possibly jointly. This paper proposes a different approach that considers ...

An antioxidant mechanism of tetrahydrocannabinol (THC) and cannabidiol (CBD) were compared with a simplified model of α-tocopherol, butylhydroxytoluene and hydroxytoluene in order to understand the antioxidant nature of THC and CBD molecules using DFT. The following electronic properties were evaluated: frontier orbitals nature, ionization potential, O-H bond dissociation energy (BDEOH), stabil...

Deregulation, re-regulation and continuing globalisation embody an imperative that banks increase efficiency in order to survive. We employ the Simar-Wilson (2007) two-step double bootstrap Data Envelopment Analysis method to measure whether cost efficiency among Jamaican banks has improved between 1999 and 2009 following a number of post-crisis responses aimed at strengthening and improving th...

This paper assesses the differences in technical efficiency of, and cassava production systems employed by, male-managed (MMF) female-managed (FMF) farms Fanteakwa District of Ghana. The study employs translog stochastic meta-frontier model to analyse data obtained from 300 randomly selected smallholder farmers finds an average metafrontier (MTE) 0.06 0.03 among MMF FMF respectively. technology...
